Abstract

Optimization of a high-throughput screening hit led to the discovery of a new series of 5-phenoxy-1,3-dimethyl-1H-pyrazole-4-carboxamides as highly potent agonists of TGR5. This novel chemotype was rapidly developed through iterative combinatorial library synthesis. It was determined that in vitro agonist potency correlated with functional activity data from human peripheral blood monocytes.
